Specification of Letters Patent.

Patented July 25, 1905.

Application filed May 13, 1905. Serial No. 260,318.

To rtZZ whom, it may concern.-

Be it known that I, LOTI-IAR WV. FABER, a citizen of the United States,residing in the borough of Manhattan, city of New York, in the countyand State of New York, have invented a certain new and usefulImprovement in Lead-Pencils, of which the following is a specification.

The invention relates particularly to lead pencils of the type carryingat one end an erasive, such as rubber. Heretofore such an erasive hasbeen secured in position by means of a tube, and in some instances suchtube has been made of paper of one or more thicknesses, so as to enablethe same to be cut away to expose the erasive after the same has becomeworn down by use. Much difficulty, however, has been experienced withstructures of this type. To some extent users have \vastefully discardedpencils so constructed rather than go to the trouble of removing aportion of the tube to expose the erasive. Occasionally in cutting awaythe tube the erasive is cut away as well, and even where this does notoccur the tube is often removed unevenly, with the result of exposing asubstantial portion of the erasive at one point and little or none atanother. Where this occurs and an erasure is attempted by contact at thelatter point, the blurring or smirching of the writing is inevitable.These and other difiiculties are wholly overcome by the presentinvention, in accordance with which I employ a tube, preferably of paperor other easily-cut material, secured at one end to a pencil, itssurface lying flush therewith, and at the other end provided with anerasive, such as rubber,cemented or otherwise secured thereto. Adjacentto its outer end and in proximity to the erasive I provide the tube witha series of indicating lines, marks, or grooves parallel with each otherand with the end of the tube, whereby means are afforded for assuringthe even cutting away of the end of the tube for the exposure of theerasive. \Vhere grooves are employed for this purpose, the act ofseparating successive parallel rings of the tube material is muchfacilitated, it being necessary only to run a knife-blade around thegroove and then remove the ring of material separated thereby.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is an elevation showing the end of a pencil employing myinvention. Fig. 2 is a sectional view, the erasive being shown in elevation; and Fig. 3 is an enlarged sectional view of a portion of thetube shown in Figs. 1 and 2.

Referring to the drawings, in which similar letters of reference denotecorresponding parts, A designates the pencil, provided at one end withthe tenon a, which may be integral with or secured to said pencil.

B designates a tube,preferably formed of paper, textile fabric, or othereasily-cut material and of one or more thicknesses, as desired. Withinsuch tube is secured in any suitable manneras, for instance,by means ofcementthe erasive (J, of rubber or other material, said erasive normallyprojecting beyond the end of the tube B. The indicating medium on saidtube is shown in the drawings in its preferred form, the same beingprovided with a series of annular depressions or grooves 7), parallelwith each other and with the end of said tube. In practice such groovesare preferably formed by stamping or rolling the material of which saidtube is composed, the effect being to decrease the thickness of suchmaterial along the lines of such grooves, so that but slight incision bythe knife-blade is required to separate a section of the tube andcorrespondingly expose the erasive. Moreover, the removal of eachsection makes the exposure of the erasive uniform in degree along thesides thereof, no projecting portions being left to blur or smirch thewriting when such erasive is employed. I do not desire to be limited tothe use of the annular depressions or grooves in the tube, however, as Imay, if desired, substitute therefor equivalent means-such,.forinstance, as lines marked upon the exterior of the tube parallel witheach other and with the end of such tube.

At the junction between the pencil A and the tube B, I prefer to employan annular band 72, secured, preferably by means of an adhesivematerial, over such junction, concealing the same, binding the partsfirmly together, and giving the pencil as a whole a finished appearance.

Having now described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is as follows:

1. A pencil having a tube of easily-cut material, such as paper, securedat one end to such pencil and carrying an erasive at its other end, saidtube having, adjacent to its erasivecarrying end, annular indicatingdevices substantially parallel with each other and with the end of saidtube, substantially as described.

2. A pencil having a tube of easily-cut material, such as paper, securedat one end to such pencil and carryingan erasive at its other end, saidtube having, adjacent to its erasivecarrying end, annular recesses orgrooves substantially parallel with each other and with the end of saidtube, substantially as described.

3. A pencil having a tube of easiLy-cut material, such as paper, securedat one end to such pencil and carrying an erasive material at its otherend, said tube having, adjacent to its erasive-carrying end, annularrecesses or grooves substantially parallel with each other and with theend of said tube, and, adjacent to its other end and coacting therewithand with said pencil, an annular band, substantially as described.

This specification signed and witnessed this 11th day of May, 1905.
